What’s the sad story about how painful it is to live after a broken love?

You don’t know how naughty your shadow is. It’s always dangling in front of my eyes, making me unable to work with peace of mind and unable to concentrate on eating. I really want to open your head and see if it contains poop that makes you so sick. I don’t know if the decision I’m making now is the right one, but I only know that if you weren’t by my side, I would be like a soulless puppet, wandering alone in this strange city without anyone. Will know the pain in my heart. We were together for three years, you said you loved me, but we broke up. When we are together, we are always noisy, and we always quarrel over trivial things. We broke up, you said our personalities were incompatible, we broke up. You said that we have different views, you said that we are not from the same world, and we broke up. You said you loved me, but you still left me. You said I didn't understand you, and I didn't know what I did wrong. We broke up. I don't know whether the decision I made now is right or wrong, but I know that you no longer belong to me.
